Sigh, it is a silly v2->v3 rebase mistake, a change hunk that should be
in patch 4 ended up in patch 3, series as a whole is fine but this must
be fixed.

Rafael, please let me know the best way to handle this, I think
me sending a v4 is the simplest so that you can just update the branch.

Apologies and thanks.

Lorenzo
